I had the Bluefin in my car for two days - unit now returned within the 7 day period which was a shame as superchips customer service is top rate. The reasons for this were as stated below and should be considered not only wrt Superchips but also all the other Tuning products;
1. The 'bird' noise the turbo made during spool up did make me worry about longevity. Even though Superchips do appear to offer good warranty i do not wish to be stranded until repair.
2. On full welly the power deliver felt fine however in normal mode driving between 3.5k to 4k the power delivery was a bit 'spikey' which means that you have to drive round it and therefore at times it removed some enjoyment (flow) from the car. I have owned a EVO VIII MR340 which was a big boost car but it did not have the same characteristic. This spikey trait has also been experienced by another forum member
3. I think the bluefin application (and indeed any chip) would be better suited to a 4 wheel drive car - i found there is a loss of 2nd gear fun as i have to wait to put the car in 3rd before i can enjoy it. A Golf is not as throttle adjustable as say a Caterham or indeed a 205 GTI to modulate power to max effect in 2nd without wheel spin.
4. Personally i like the standard character of the engine where the pull increases as you get nearer the top end of the rev range (makes a good noise too!). Bluefin makes it 'feel' as if the power is all lumped in the middle.
5. In the normal golf GTI the 250hp map that is offered could be better suited to the 2 wheel drive configuration - close to the standard ed30 - and indeed superchips has a top asset in that it has access to real time longevity data from the VW Racing UK cars - however for the ED30 no matter what tuning firm you use none of them have real time longevity experince except that from the owners - us the guinepigs! - i have no idea whether the transmission can cope with an addtional 60+hp over long sustained periods of time. Alternatively if the tuning companies could find out how much safety factor is left in each of the componenets this would allow the owners some form of confidence - case in point when you phone the tuning companies do they know the tollerances of the relevant components - turbo etc...
6. The standard map feels more 'polished' and to me this is no suprise - has any one have any idea how much a major manufacturer spends on map research over a tuning company? - i would bet it were a lot more and the driving experince would back this up IMO.
I tried the bluefin on a 'b' road and indeed the car was faster but somehow because you didn't need to push so hard it wasn't any more fun than the standard set up (at this point i got a 14mpg average!!!!) Addtionally i ran the car at a steady 80mph on the motorway and stopped during the same journey to return the car back to the standard map and instantly there was a 3MPG gain (27 to 30).
Having tested the difference i was actually glad to get the old car back - i missed its character with the Bluefin!
Still all down to personal preferences i suppose - i use the Golf as a fast road car - if you want something else i'd suggest you forget the Golf and get something a little less lardy!
